EHG Series

Electrolytic Hydrogen Generator

Our Electrolytic Hydrogen Generator (EHG) is capable of producing high purity hydrogen at 99.999% purity directly from water efficiently without harmful by-products, contaminants, and pollutants. The by-products are only water and oxygen. This is the safest generation method available today.

The EHG produces only molecular hydrogen without hypochlorous acid and has no risk of contamination from the electrode coatings.

Our sophisticated electronic control system enables the EHG to continuously and reliably operate at high performance levels and has the longest life span in the industry.


Hydrogen purity ≥ 99.999%

Consistent production

Without Hypochlorous acid & Ozone

Reduced equipment size & maintenance

Instant production without waiting

Without liquid eletrolyte addition

How It Works

A electrolytic cell composed of water will split into oxygen and hydrogen gas, hydrogen atoms are discharged at the cathode, while oxygen atoms are generated on the anode interface and polymerized into ozone molecules at a concentration of 28 wt%.


Membrane Electrode Electrolysis (Proton Exchange Membrane)

Uses Water and a Deionization Filter

The principle of membrane electrode electrolysis hydrogen production is the use of low-voltage DC-conducting solid-state membrane electrodes for positive and negative electrode electrolysis deionized water. Water is separated into hydrogen and oxygen atoms in the form of proton exchange at a special anode interface. Oxygen from the anode is directly discharged, and hydrogen is polymerized at the cathode into hydrogen molecules. The purity of hydrogen produced by the electrolysis method is about 97% or higher.

The by-product of the hydrogen generation by electrolysis is oxygen, and no additional electrolyte is required.

Magnesium Water Production Method (Chemical Reaction)

Uses Water and Magnesium

Hydrogen is generated by the reaction of magnesium rods or magnesium balls with water, and the by-product is magnesium oxide or magnesium hydroxide.

Since hydrogen cannot be effectively dissolved in water, it can be collected as drainage gas. The reaction chemical formula is as follows: Mg+2H2O → Mg(OH)2+

Direct Electrolysis (Alkaline Water)

Uses Water and Electrolytes

An electrolyte is added to the electrolytic cell through which the water flows, and an electric current is conducted to dissociate the water molecules. The cathode of the DC electrode generates hydrogen gas; the anode generates oxygen.

Since hydrogen cannot be effectively dissolved in water, it is possible to collect hydrogen and oxygen by means of a drainage gas collection method, the volume of which is 2:1.

The electrolyte may be an ionic compound of a strong acid and a strong base, for example, sodium chloride, but in order to prevent the anode from generating chlorine, sodium hydroxide should be used as the electrolyte.
